Abstract: This paper presents the results of an experimental study for evaluating the use of external fiber-reinforced polymer (FRP) laminates for strengthening unbonded posttensioned concrete members. Twenty-four full-scale simply ...

Abstract: This paper presents a synthesis of the results of a broad experimental and analytical research program undertaken for evaluating the flexural behavior of unbonded posttensioned prestressed concrete (PC) members when ...

Abstract: This paper describes the behavior of geogrid–reinforced concrete members. The application of geogrids in concrete constitutes a new dimension for using geosynthetics in infrastructure. In pavement applications, geogrids ...

Abstract: This paper presents the results of a three-dimensional (3D) finite-element study that investigated the effect of the multipresence factor of the load-reduction factors used in the AASHTO Bridge Design Specifications. Typical ...
